[0053] In order to solve the problems of the prior art, this embodiment provides a method for determining the industrial link to which a data element belongs. First, the data element is obtained and the data field corresponding to the data element is determined, wherein the data field includes one field or multiple fields. Then, based on the data field, the search formula corresponding to each industrial link is written, and the data element is matched with the search formula of each industrial link to obtain a matching result, and the matching result is used to reflect the hit situation of the search formula of each industrial link in the data element.

[0054] The method of determining the industry link to which a data element belongs in this embodiment can be applied to: Figure 1In the application environment shown, the terminal 102 communicates with the server 104 through a network. The data storage system can store data that the server 104 needs to process. The data storage system can be integrated on the server 104, or placed on the cloud or other network servers; the method for determining the industrial link to which the data element belongs can be executed by the terminal 102 or the server 104, or can be executed by the terminal 102 and the server 104 in collaboration.

[0055] The terminal 102 may be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, an IoT device, and a portable wearable device. The IoT device may be a smart speaker, a smart TV, a smart air conditioner, and a smart vehicle-mounted device, etc. The portable wearable device may be a smart watch, a smart bracelet, a head-mounted device, etc.

[0056] The server 104 may be an independent physical server or a service node in a blockchain system, wherein each service node in the blockchain system forms a peer-to-peer network.

[0057] In addition, server 104 can also be a server cluster composed of multiple physical servers, and can be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDN), as well as big data and artificial intelligence platforms.

[0058] The terminal 102 and the server 104 may be connected via Bluetooth, USB (Universal Serial Bus) or a network or other communication connection method, and this application does not impose any limitation thereto.

[0059] In some embodiments, Figure 2 As shown, a method for determining the industrial link to which a data element belongs is provided. Figure 1 The server or terminal in the Figure 1 The server and terminal in the method are executed in cooperation with each other. Figure 1 The server execution in is taken as an example to illustrate, including the following steps:

[0060] Step S100: Acquire a data element, and determine a data field corresponding to the data element, wherein the data field includes one field or multiple fields.

[0061] This embodiment first obtains data elements, which are data elements that need to be put on the chain, that is, data elements that need to be classified and marked with industrial links. In this embodiment, data elements may include enterprise data elements, university data elements, personal data elements, patent data elements, product data elements, project data elements, etc. The data fields associated with different data elements are complex and diverse, and the importance of data fields in different industrial links is also different. For example, in the software industry, information on software copyright is more important, so the data fields of the corresponding data elements are fields related to software copyright.

[0062] In one implementation, when determining the data field, this embodiment includes the following steps:

[0063] Step S101, obtaining industry characteristics;

[0064] Step S102: Based on the industry characteristics, determine the data field corresponding to the data element, and the data field matches the industry characteristics.

[0065] In order to accurately manage and classify data elements, combined Figure 3 As shown in the flowchart of data elements on the chain, this embodiment first defines the industrial chain map in the form of a tree diagram. The industrial chain map starts from the top of the industrial chain (such as raw materials) and is refined step by step to the end link (end product). The industrial chain map includes multiple nodes, and each node represents a link in the industrial chain. The lines between the nodes represent the association and dependency between the links. In this way, the structure and process of the industrial chain can be clearly displayed, providing a clear framework for subsequent data chaining. This design allows the chain results to be aggregated from the end to the top, and the data granularity from coarse to fine from top to bottom can be consistent with the real data situation, thereby improving the recall and accuracy of data chaining.

[0066] In order to accurately determine the industrial link to which the data element belongs, the present embodiment obtains the industrial characteristics. According to the different industrial characteristics, the present invention allows the setting of differentiated data fields for different industrial links or different subjects. Taking the enterprise data element as an example, the data fields corresponding to the enterprise data element include but are not limited to the enterprise profile, enterprise patent information, enterprise project information, etc. It can be seen that the data field of the present embodiment is related to the industrial characteristics. In addition, the data field of the present embodiment can be one field or multiple fields. Therefore, the correspondence between the data element and the data field can be a one-to-one relationship or a one-to-many relationship. When there are multiple data fields, the present embodiment can be analyzed based on multiple data fields to accurately determine the industrial link to which the data element corresponds. For example, taking the patent data element as an example, the data fields that can be set in the present embodiment are: award library, innovation platform library, scientific research institution library, university library and other fields.

[0067] In addition, in other implementations, when determining the data field, this embodiment also customizes the data field. When customizing, it can be based on the type of data element, and then further analyze the key indicators of the data element under this type, and then customize the relevant data fields based on the indicators that the terminal pays attention to. For example, first determine whether the type of data element is an enterprise data element or a university data element, and then determine the key indicators of the enterprise data element, or determine the key indicators of the university data element, such as the key indicators of the enterprise data element are enterprise projects, so you can customize the data fields related to the enterprise project. For another example, when the key indicator of the university data element is patent information, you can customize the data fields related to the patent information. This embodiment is conducive to enriching the data fields and helping the accurate classification of data elements by customizing the data fields.

[0068] Step S200: based on the data field, compile the search formula corresponding to each industrial link, and match the data element with the search formula of each industrial link to obtain a matching result, wherein the matching result is used to reflect the hit status of the search formula of each industrial link in the data element.

[0069] In order to determine the industrial link to which the data element belongs, this embodiment can determine the search formula for each industrial link. In this embodiment, the search formula is used to reflect the logical relationship between data fields. For this reason, this embodiment can write a search formula for each link based on the determined data field. When writing the search formula, it is mainly written based on the rules and logical relationship between fields in the data field. Then the data element is matched with the search formula of each link. The purpose of matching is to determine the hit situation of the search formula of each industrial link in the data element, so as to classify the data element based on the hit situation.

[0070] In practical applications, this embodiment can obtain an industrial chain map, and then determine several industrial links in the industrial chain map, such as the industrial links in the semiconductor and integrated circuit industry chain include: design link, manufacturing link, packaging and testing link, equipment link, material link, EDA link, IP link, and parts link, etc. This embodiment can set a corresponding search formula for each industrial link. In subsequent steps, the search formula of each industrial link can be matched with the data element to obtain a matching result. The matching result of this embodiment reflects the hit situation of the search formula of each industrial link in the data element. For example, taking the EDA link as an example, when the data field includes fields such as company profile, patent IPC, patent title, software copyright, project title, project type, etc., this embodiment can write a search formula based on the rules and logical relationships between fields such as company profile, patent IPC, patent title, software copyright, project title, project type, etc.

[0071] In addition, in other implementations, when writing the search formula corresponding to each industrial link based on the data field, this embodiment can be further written according to the industry characteristics, and can also obtain keywords in each industrial link. The keyword can be an indicator in each industrial link, and the key indicator can be combined with the data field to obtain the search formula for each industrial link.

[0072] Step S300: determine the relevance scores between the data elements and each industrial link based on the matching results, and determine the target industrial link to which the data element belongs based on the relevance scores.

[0073] When the matching results of the search formula between the data elements and each industrial link are obtained, the present embodiment can calculate the correlation score between the data elements and each industrial link based on the matching results. The correlation score reflects the correlation degree between the data elements and each industrial link. The higher the correlation score between the data elements and a certain industrial link, the more relevant the data elements are to the industrial link. To this end, after obtaining the correlation score between the data elements and each industrial link, the present embodiment uses the industrial link with the highest correlation score as the target industrial link.

[0074] In one implementation, when determining the relevance score, this embodiment includes the following steps:

[0075] Step S301: based on the matching results, determine the number of hits of the search formula of each industry link in the data elements;

[0076] Step S302: Obtain weight information corresponding to the data field;

[0077] Step S303: Based on the weight information and the number of hits, determine the relevance score between the data element and each industry link.

[0078] Specifically, this embodiment first determines the number of hits of the search formula of each industrial link in the data element based on the matching results, and then obtains the weight information corresponding to the data field. The weight information is pre-configured, and this embodiment can set the weight information corresponding to the data field for different industrial links. Next, this embodiment can determine the relevance score between the data element and each industrial link based on the weight information and the number of hits. The specific calculation formula is as follows:

[0079] ;

[0080] Subject to

[0081] ;

[0082] ;

[0083] in, Indicates the weight information corresponding to the data field, It represents the number of hits of the search formula of each industrial link in the data element, n represents the number of fields in the data field, and f represents the scoring method.

[0084] In this embodiment, if the number of fields in the data field is different, the corresponding scoring method is also different. Specifically, if the data field includes one field, such as a company, and a corresponding brief introduction information, then the data field of the company data element only has one brief introduction information, that is, there is a one-to-one relationship between the data element and the data field. The scoring method at this time is as follows:

[0085] ;

[0086] in As can be seen from the above scoring method, when the number of hits of the search formula of the industry link in the data element is greater than or equal to the threshold hour, Assign a value of 1; when the number of hits of the search formula of the industry link in the data element is less than the threshold hour, Assign a value of 0.

[0087] If the data field includes multiple fields, for example, a company has multiple patent data, then the data field of the company data element includes multiple patent information, that is, there is a one-to-many relationship between the data element and the data field. The scoring method at this time is as follows:

[0088] ;

[0089] , ;

[0090] ;

[0091] ;

[0092] in, Indicates the weight of the number of hits, Indicates the hit ratio weight, The calculation method of the number of hits is to use CDF to standardize the number of hits in each industry link, where represents the average number of hits, represents the standard deviation of the number of hits, is the calculation method of the hit ratio, specifically using CDF to standardize the hit ratio. Indicates the corresponding amount of data owned by the data element, is the ratio of hits to data elements, where represents the average of the hit ratio, represents the standard deviation of the hit proportion.

[0093] By calculating the correlation scores between data elements and various industrial links through the above-mentioned different scoring methods, the correlation degree between data elements and various industrial links can be determined, and then the industrial link with the highest correlation score can be used as the target industrial link corresponding to the data element.

[0094] Based on the above embodiments, the present invention also provides a system for determining the industry link to which a data element belongs, such as Figure 4 As shown in , the system includes: a data field determination module 10, a search formula matching module 20 and an industry link determination module 30. Specifically, the data field determination module 10 is used to obtain data elements and determine the data fields corresponding to the data elements, wherein the data fields include one field or multiple fields. The search formula matching module 20 is used to write search formulas corresponding to various industry links based on the data fields, and match the data elements with the search formulas of various industry links to obtain matching results, and the matching results are used to reflect the hit status of the search formulas of various industry links in the data elements. The industry link determination module 30 is used to determine the relevance scores of the data elements and various industry links based on the matching results, and determine the target industry link to which the data elements belong based on the relevance scores.
